    Pay attention to shallow snowpack areas, as this is the most likely place to trigger this deeper instability.

Weather Forecast

Mixed sun and cloud with freezing levels around 2500 m for Thursday. Friday and Saturday forecasted for flurries and freezing levels around 2100 m.

Snowpack Summary

In the alpine there is 5 -10 cm of low density new snow overtop of the previous 40-60 cm of storm snow from last week.  All aspects except true north are seeing the effects of solar heating with sun crusts forming to ridgetops. On north aspects the storm snow is bonding well to previous surfaces and is dry above 2000 m.

Avalanche Summary

Solar related loose snow avalanches up to Class 2.

Confidence

Freezing levels are uncertain
